Gabexate mesylate is a Factor X inhibitor; serine protease inhibitor . Target: Factor X Gabexate mesylate is a non-antigenic synthetic inhibitor of trypsin-like serine proteinases that is therapeutically used in the treatment of pancreatitis and disseminated intravascular coagulation and as a regional anticoagulant for hemodialysis. Values of the inhibition constant (K(i)) for gabexate mesylate binding to human and bovine tryptase were 3.4 x 10(-9) M and 1.8 x 10(-7) M (at pH 7.4 and 37.0 degrees ), respectively. Gabexate mesylate inhibited the fibrinogenolytic activity of human tryptase [1]. Gabexate Mesylate decreased the TNFalpha production of LPS-stimulated monocytes as shown by the inhibition of mRNA expression and increased theIL-10production of LPS-stimulated monocytes. Gabexate Mesylate also suppressed the NFkappaB activity of LPS-stimulated monocytes. Inhibitory effect of Gabexate Mesylate on the TNFalpha production of activated human monocytes is mediated by the suppression of NFkappaB activation [2]. Gabexate mesylate inhibits competitively constitutive and inducibleNO synthase(cNOS andiNOS, respectively), with Kivalues of 1.0×10 4M and 5.0×10 3M, respectively, at pH 7.4 and 37.0℃. gabexate mesylate increasesiNOSmRNA expression in rat C6 glioma cells, as induced byE. colilipopolysaccharide plus interferon-γ. Gabexate mesylate inhibits dose-dependently nitrite production (i.e. NO release) in rat C6 glioma cells, as induced byE. colilipopolysaccharide plus interferon-γ [3].
